Description

A kind of radio resource control RRC configuration method and relevant device

Technical field

The present invention relates to radio network technique field more particularly to a kind of radio resource control RRC configuration method and relevant devices.

Background technique

As shown in Figure 1, the configuration diagram of a kind of UE (User Equipment, user equipment) and eNB (evolved Node B, base station) double connection that Fig. 1 prior art provides.Under this framework, on the one hand, MCG (Master Cell Group controls cell group) and SCG (Slave Cell Group, subordinate cell group) can retain the carrying of oneself, and provide service to UE；On the other hand, MCG's is carried on PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) layer shunted, a part of data are sent to RLC (the Radio Link Control of MeNB (master base station), wireless spread-spectrum technology) layer, another part is sent to the rlc layer of SeNB (from base station) by X2 mouthfuls, is sent by SeNB scheduling.

In the prior art scheme, as shown in Fig. 2, Fig. 2 is the control schematic diagram that a kind of double-strand that prior art provides connects.Wireless connection between eNB and UE is sent by MeNB, when UE and SeNB and MeNB carries out double linking communications, SeNB carries out RRC (Radio Resource Control for UE firstly the need of according to situations such as the load of SCG, wireless heterogeneous networks) configuration, such as: rlc layer of the UE on SeNB, transmission configurations such as MAC layer etc., and RRC configuration content is sent to MeNB by X2 mouthfuls, then the RRC of MCG and SCG is configured while being sent to UE by MeNB, but in transmission process, part RRC configuration content will continue to be sent to SeNB by X2 mouthfuls again, UE is sent to by SeNB.Due to the signaling of SeNB have passed through 2 times X2 mouthfuls, will lead to the increase of SeNB transmission delay, in addition, if UE is attached with multiple SeNB, the RRC configuration content of multiple SeNB requires to be sent by MeNB, will lead to the RRC signaling load excessive of MeNB.
